Gemini Rising by Bianca Swan
The Alastair twins are a scientific impossibility. To parents who’ve tried every way to have a child, their male and female identical twins are a miracle.
Isolated in their island castle, the twins Alain and Alina turn to each other for friendship and love. But when their love shifts from fraternal to frighteningly deep, they’ll each dance with their lust in their own way.
A dark fantasy of forbidden longings and midnight pledges, spoken to be broken...or to be kept. How can these phenomenal twins possibly unleash their innermost desires? The answer will shock you.
